Robust change point tests by bounded transformations [PDF]
arXiv, 2019 Classical moment based change point tests like the cusum test are very powerful in case of Gaussian time series with one change point but behave poorly under heavy tailed distributions and corrupted data. A new class of robust change point tests based on cusum statistics of robustly transformed observations is proposed. This framework is quite flexible,

Change Actions: Models of Generalised Differentiation [PDF]
arXiv, 2019 Cai et al. have recently proposed change structures as a semantic framework for incremental computation. We generalise change structures to arbitrary cartesian categories and propose the notion of change action model as a categorical model for (higher-order) generalised differentiation.

Online Causal Structure Learning in the Presence of Latent Variables [PDF]
arXiv, 2019 We present two online causal structure learning algorithms which can track changes in a causal structure and process data in a dynamic real-time manner. Standard causal structure learning algorithms assume that causal structure does not change during the data collection process, but in real-world scenarios, it does often change.

DUALISME DALAM SEKTOR MANUFAKTUR INDONESIA: SEBUAH UJI HIPOTESIS DENGAN ANALISIS INPUT-OUTPUT
Jurnal Manajemen dan Wirausaha, 2006 According to standard literature on development economics, development processes may cause dualism. Dualism means that there are huge sectors (or regions) with modern technology as well as small sectors (or regions) with traditional technology. As far as

Bias and population structure in the actuation of sound change [PDF]
arXiv, 2015 Why do human languages change at some times, and not others? We address this longstanding question from a computational perspective, focusing on the case of sound change. Sound change arises from the pronunciation variability ubiquitous in every speech community, but most such variability does not lead to change. Hence, an adequate model must allow for

Structural Changes and Percolation Transition in Networks after Aging Processes [PDF]
arXivIn social networking services, users constantly change, and the network structure changes simultaneously. As the network structure changes, so does the word-of-mouth within it. To study how information transfer on the network changes with the aging of the network, we investigated the relation of the structure and the percolation in the aged networks ...

A deterministic sublinear-time nonadaptive algorithm for metric $1$-median selection [PDF]
arXiv, 2015 We give a deterministic $O(hn^{1+1/h})$-time $(2h)$-approximation nonadaptive algorithm for $1$-median selection in $n$-point metric spaces, where $h\in\mathbb{Z}^+\setminus\{1\}$ is arbitrary. Our proof generalizes that of Chang.
